IMPROVEMENT IN NUT-LOCKS.

Specification forming part of Letters Patent No. [80,414, dated August1, 1876; application filed January 15, 1876.

. provement in Lock-Washers; and we do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofrefer-- ence marked thereon.

' Figure 1 of the drawings is a representation of a side elevation ofour lock-washer, and

Fig. 2 is a transverse sectionalview of the same. Figs. 3 and 4 aredetailed views, and Fig. 5 is a transverse sectional view.

This 'nventiou has relation to nut-locks for railroad-rails and otherpurposes; andthe nature of our invention consists in constructing theplate, known as the locking washer-plate, with a long bearing baseadapted to rest upon. the base-flange of the rail, and to be bentbeneath the lower beveled edge of the fish-plate used in splicing therail, as will be hereinafter explained.

1n the annexed drawings, A A designate the ends of two sections ofrailroadrails,

which are of the Well-known T shape, and which are spliced together bymeans of fishpla-tes secured on opposite sides of the necks of thesections by means of bolts B and nuts 0. The bolts B are prevented fromturning by forming flattened and tapered enlargements on them near theirheads, which enlargements are received in recesses of correspondingshape made in the fish-plate D. The opposite end of the bolt B passesthrough the fish-plate D, which has beveled edges a a similar to thefish-plate D. The fish-plates on both sides of the rail are of the samesize and shape, and are usually of the same length.

E designate washers, which are perforated to receive through them thebolts B, and constructed with angles 12 and also with broad extendedbase pieces 0. These washers lie flat against the fish-plates, and whenthe nuts are screwed home one of the angles b is bent over each nut,thus holding it firmly. The base-piece c of each washer is then drivenunder the-lower beveled edge a of the fishplate, which secures the wholefirmly, and prevents washer and nut from turning. In the .If, in bendingback one of the angles 1), it

should break oft, either one or the other of the angles 1) can be used.

Figs. 4 and 5 show a Washer, having a spring-loop, b, ot'rectangularform, for holding the nut from turning. This washer has the same form ofextended base as described for the washer of Figs. 1, 2, and 3, andafter the nut has been driven home this loop will be sprung up,encompassing three sides of the nut, and will effectually hold itagainst casual backward displacement.

What we claim as new, and desire to secure by Letters Patent, is-

1. In combination with the fish-plate D, having a lower inwardly-beveled edge, a, the washer E, having an extended base-part, 0, adaptedto be bent inwardly against the beveled edge of the fish-plate, and torest against the flange of the rail, substantially as specified. I

2. In combination with a bolt, B, fish-plate D, with lower beveled edgea, prismatic nut c, and the flange of a railroad rail, the washer E,having rectangular loop-b adapted to be bent up over the nut and anextendedbase 0, adapted to be bent into the lower beveled edge of thefish-plate, and to bear against the flange of the rail, substantially asspecified...

In testimony thatwe claim the above we have, hereunto subscribed ournames in the presence of two witnesses.
